Zoom Whitening Treatment

I did my zoom whitening treatment yesterday, I didn’t feel anything while doing the treatment so I did all 4 sections, but after the treatment I am experiencing pain, today I still woke up with my teeth sensitive hopefully it be gone soon... I wud definitely recommend people to do this treatment because it work if you don’t mind dealing with some pain after then doit you won’t regret it, I have a beautiful smile now!! Here are some pictures of before and after, I hope this can help
